Mk5/Mk6 Golf/Jetta, B6 Passat, CC, Tiguan, EOS ECU Removal

**NOTE: Some ECU’s are located under the wiper rain tray while others are

next to the battery!

Pop your hood and look to see if an ECU is next to your battery. If not then

proceed to the instructions on the next page. If it is you’re in luck and the ECU can be removed very easily in about a minute.

Removal Instructions for ECU’s under rain tray

1. Remove the wiper caps (yellow). Remove the bolt under the cap (purple). lift the arm of the wiper (red)

2. Rock the wiper back and forth till its off the thread (yellow)

3. I didnt get a pic of removing the rain tray but its pretty easy.. just remove the liner and pull up and out on the rain tray and it will seperate. This pic is of the missing rain tray (yellow) and the exposed ECU (red)

4. These are the two infamous blank screws (yellow) that hold the ecu against the "cradle"

5. Now remove to screws to the removable guard (yellow).. ones on the far left near the coolant ball and the right one is near the battery.

6. This is the driver side of the guard (yellow) that has the screw (red) near the battery

7. I just dremeled the faceless screws (yellow). too easy.. i love my dremel

8. Unscrewing (yellow) the faceless screws (red) that have been dremeled

9. Work the Ecu out of the slot by sliding towards the driver side. NOTICE that i bent the cradle holders (yellow to red) right side to ease it out. you can do this IF YOU WANT .. since its strong enough to go back into place when i install the ECU it doesnt matter to me.

10. The ECU is out! but wait i have two thick cables still attached

11. The two big cables connected to the ECU are secured by drawer clips (yellow). just pull outward

12. The drawer (yellow) is completely pulled to its fullest position

13. Once you pull the drawer clip out (yellow), pull the connector (red) out. *Do this to the driver side one too*

14. Remove ECU completely from the car!
